Here’s this week’s question:
I can’t wait to teach my full day course, SQL Server Index Formulas: Problems and Solutions in Seattle at the PASS Summit on Tuesday, October 25th. Woot! Less than 3 weeks away!
As you tweak and test queries, it’s awfully useful to see how the performance has changed.
What tools in SQL Server will notify you about blocking and help track the queries behind your toughest blocking and deadlocking problems?
Every query tuner wants to explain exactly how much faster we made a query.
But sometimes SQL Server Management Studio adds noticeable overhead to the query duration. For relatively fast queries that return more than a few rows, just the overhead of displaying the results can skew your duration metric.
Should you always index your foreign keys? What if you index them, and then the index never gets used?
